Dragonfly is a high quality modular data acquisition system intended for applications ranging from ultra-portable small channel count mobile field based needs to large scale fixed installations of hundreds of synchronous channels.

Dragonfly is completely compatible with HGL’s existing range of data acquisition, real-time monitoring, analysis and archiving systems, and due to its network based architecture can be integrated into 3rd party or customer bespoke systems with ease.

Dragonfly is small enough to fit easily in a laptop bag, and lightweight enough (at < 1 kg) for easy transport to remote sites. As such it makes an ideal measurement system with a standard laptop for personal / consultancy field work. However, the standard Dragonfly is also able to be linked with other units to create large multi-purpose systems simply by sliding it together with one or more other modules, and connecting a few simple cables (power, sync, and Ethernet).

Dragonfly can be fitted with a number of internal signal conditioning cards which further extend its capabilities and benefits to end users. Single or multiple conditioning functions can be hosted by an individual Dragonfly and cards can be swapped out by users if required.

The DragonflyIRIG module obtains its time-stamp and clock synchronisation signal from an analogue IRIG-B signal connected using an auxiliary connector on the rear of the unit. This can be used to synchronise data between a Dragonfly-based system and external third-party systems, or it can be used to synchronise distributed Dragonfly units that are too far away for direct LVDS synchronisation as found on the standard Dragonfly module.
